vices, and more particularly to an illumi- 1g nating display sign. 7

One of the principal objects of the invention is to provide a sign constructed so that a the advertising matter will be clearly dis cernible in the daytime, andin the nighttime by.means of asource of light.

Another object of thelinventio'n is to provide a sign including asign card or mask having the advertising matter out therefrom, said mask being of a dark color and placed with relation to a white translucent glass, so that the latter may be viewed through the advertising matter to set out the letters and words forming the latter in the daytime, the letters being set out at night by means of a source of light placed beyond the translucent glass, the construction of the device being such that the masks containing the advertisingmatter may be exchanged when desired.

An additional object of the invention is to provide a device of the class described which will be simple, durable, efficient in operation, and inexpensive to manufacture.

With these and other objects in 'view which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter more fully described and claimed and illustrated in the accom- 40 panying drawing in which like characters of reference indicate like parts throughout the several figures, of which Figure 1, represents a front elevational view of the device, Fig. 2,'represents a rear elevational view of the display frame, Fig. 3 represents an enlarged vertical transverse sectional viewtaken on the plane indicated by the line 33 of Fig. 1, looking in the direction indicated by the arrow, Fig. 4, represents a horizontal sectional view taken on the plane indicated by the line H of Fig. 3,. Fig. 5, represents a side elevational view of the display frame showing the manner of placing the mask'therein, and, Fig. 6, represents a fragmental perspective view of one corner of the translucent glass holder.

Fig. 7 represents an enlarged fragmentary sectional view indicating the'manner of the disposition of the colored tissue.

Referring more particularly to the drawing, the device comprises what may be termed a display. frame A detachably cured by means of hooks 5 to an illuminat ing or light holding box B. The latter is substantially rectangular in shape and is closed on all sides except one, upon which latter side the display frame is adapted to be secured when the device is in operative position." The light box is provided with four long, straight electric light globes 6, disposed one above the other in pairs in the rear corners of the box, and adapted to refleet light by means of angularly arranged mirrors 7 against and through apane of translucent white glass 8 carried by an inner rectangular frame 9 disposed within rabbets cut in the inner edges of the display frame. A, said inner frame at its rear edge lying flush with the rear edge of the display frame and in turn having its forward inner edges rabbeted to. receive the translucent glass 8, the latter being maintained securely in place by means of a strip of metal or other suitable material 10, secured onthe forward edges of the inner or glass holding frame.

The depth of frame!) is somewhat less in depth than the rabbet provided in the frame A, and interposed between the bottom of last said rabbct and the frame 9, and supported by frame A, is a sheet of transparent glass 11. The inner frame 9 is hinged at its lower edge as at 12 to frame A, and may be secured in position therein by means of turn buttons 13 carried by the upper edge of the latterframe. .1 1;.

The letters forming the advertising matter, are stamped or cut from what may be termed a mask 14 which comprisesa sheet of 'carboard or other suitable material whose front face is preferably of a dark color,-or of some color strongly contrasting with white, and the mask is of a shape to fit within the binding strip 10, and against the translucent glass 8, and the mask is preferably of a thickness equal to the thickness of the binding strip, so that when in assembled position, as indicated in Figs. 3 and 4, the mask will be securely held in position between the transparent and translucent sheets of glass, and will be supported at its edges by means of the binding strip 10.

Edd

By the construction described, it is evi-' dent that by reason of the white translucent glass 8 being discernible through the letters 15 of the mask, the latter will be vividly disclosed in the daytime against the background of the remaining portion of. the mask, and that at night upon the lighting of the lamps 6, a very effective and attrac tive illumination of the letters will be attained by reason of the light passing throu h translucent glass8. 4

Although the best result may be attained that the mask contained by the frame may be exchanged for another.

The device is extremely simple in construction and yet effective and efficient in its operation, and may be assembled and taken apart in a very short time and with a minimum of trouble, and may be readily I transported from place to place.

Although I have described the preferred embodiment of my invention, 1 may desire to make such changes in the construction, combination and arrangement of parts thereof as do not'depart from the spirit of the invention and the scope of the appended claims.

I I claim:

1. A device of the class described comprising an illuminating box, a display frame adapted to be detachably secured thereto,

said frame having its inner edges rabbeted at the back, an inner frame adapted to be disposed within the rabbet, said inner frame being hinged to the display frame, said inner frame having its forward inner edges rabbeted, a sheet of translucent glass disposed within the rabbet in the frame, a binding strip secured to said inner frame over the edges of said glass, a sheet of transparent glass disposed within the rabbet of the display frame, and a mask disposed between said panes of glass, said mask comprising}. sheet of suitable material disposed against the translucent glass and supported at its edges by the binding strip, said strip and mask being of substantially the same thickness. I i I 2. A device of the class described, comprising a display, frame, an inner frame hingedly connected therewith, a sheet of translucent glass supported by the inner frame, a sheet of transparent glass supported by the display frame, a binding strip for securing said translucent glass to the inner frame, and a mask comprising a sheet of suitable material adapted to be disposed against said translucent pane and between the same and said transparent pane, said mask being supported at its edges by said binding strip.

' 3. A device of the class described comprising a display frame, an .inner "frame associated therewith, a sheet of translucent glass supported by the inner frame, a sheet of transparent glass supported by the display frame, a sheet of material having advertising matter in the form of characters thereon and disposed between said panes of glass and a binding strip carried by the inner frame between the glass panes and adapted to support saidsheet of materialin position.
